Surface water levels increased in parts counties Wexford and Kilkenny overnight as heavy rainfall persisted into the early hours of this morning.
The rainfall led to road closures in places while more homes and businesses have been impacted.
A status yellow rainfall warning for counties Carlow, Dublin, Kilkenny, Louth, Waterford, Wexford and Wicklow expired at midnight, as the clean-up operation now gets under way.
Council crews will this morning begin to assess the impact of this latest round of inclement weather.
Parts of south Co Wexford appear to have suffered worst from the late night/early morning conditions.
A number of properties flooded in Bridgetown despite Wexford County Council's efforts to pump water since yesterday evening.
In Our Lady's Island, lake levels breached the bank in the village, and the road there is flooded.
While in Enniscorthy, the quays have reopened to traffic after being closed for a time overnight, with just The Promenade now remaining closed due to flooding.
Several homes and businesses in parts of Co Kilkenny, including Graiguenamanagh, Inistioge and Thomastown remained under several metres of water last night after the rivers Barrow and Nore burst their banks.
The relevant authorities will now be hoping for a reprieve in the rainy conditions of recent days to allow river levels to go down, and the damage caused be fully inspected.
However, further unsettled weather is expected for most of the long weekend.
Meanwhile, Wexford County Council said multiple roads were closed across the county due to flooding following bad weather conditions.
The council said there were "accumulations of water on roads across the county" yesterday.
The council advised road users to travel "with extreme caution" over the next 24 hours.
"Even where rivers are not currently overflowing, the risk of flooding remains very high over the next 24 hours," it added.
Dublin Racing Festival
Horse Racing Ireland has cancelled the first day of the Dublin Racing Festival.
Meanwhile the Government is to increase the amount of money available to small businesses affected by Storm Chandra which cannot get flood insurance from €20,000 to €100,000.
It will be signed off by the Cabinet in the coming days, potentially during an incorporeal meeting before the weekly Cabinet meeting on Wednesday.
